Description

LY2784544 is highly potent and selective mutant JAK2 (V617F) inhibitor with an IC50 of ~55 nM. It also inhibits IL-3-activated wild type JAK2 with an IC50 of 2.26 μM. Similarly in the proliferation assay, LY2784544 shows anti-proliferative activity in JAK2 V617F-driven cells with an IC50 of 68 nM, compared to 1.36 μM in wild type JAK2-driven cells and 0.94 μM in JAK3-driven cells. LY2784544 significantly inhibits STAT5 phosphorylation in JAK2-V617F Ba/F3 xenografts. Currently LY2784544 is being investigated in a clinical trial for the treatment of essential thrombocythemia, polycythemia vera, and primary myelofibrosis.

How to use

In Vitro:

LY2784544 was used at 5-10 µM final concentration in vitro and in cellular assays.

In Vivo:

LY2784544 significantly inhibits STAT5 phosphorylation in JAK2-V617F Ba/F3 xenografts with a Threshold Effective Dose 50 (TED50) of 12.7 mg/kg. LY2784544 also reduces JAK2-V617F Ba/F3 tumor burden in the JAK2-V617F-induced MPN model with a TED50 of 13.7 mg/kg after oral treatment. LY2784544 has no effect on CD71/Ter119 positive erythroid progenitors in spleens of SCID mice after oral treatment.
